This invention relates to an improved window construction of the doublehung sash species, and it has more particular reference to a structurewhich is principally character- .1 ized by an all metal window frame andsash construction.

In carrying out this invention we have evolved and produced a novelstructural organization expressly-made to accomplish such 1 desirableresults as smooth and quiet in operation, weather and water proofjoints, sinnplicity in construction, economy in manufacturing andinstallation and positive and dependable action.

A salient feature of the complete structure is the improved metal framewhich is distinguished from known structures in that it embodies hollowvertical stiles connected at their upper ends to an individual form ofhead jamb, and connected at their lower ends with a special type ofmetal sill plate.

An equally important feature is predicated upon the use of new sashguides, and an equally new inullion post at the center.

construction and utilization of the vertical stiles as housing forboxing-s for the sash Weights and cords, and the provision of suitablycovered openings permitting access to be to had to the interior formaking repairs.

Then too, the window sashes themselves are of special design to provideweather proof joints, smooth operations and lightness in weight.

Other features and advantages of the invention will become more readilyapparent from the following description and drawings.

In the drawings wherein like numerals indicate like parts:

Figure 1 is a front elevational view, on a reduced scale ofthecompletewindow construction.

Figure 2 is a vertical sectional View of a fragmentary nature, throughone side of the structure.

Figure 3 is a horizontal sectional view showing the internalconstruction of one vertical style, and construction and arrangement ofthe central mullion post.

Particularly do we wish to emphasize the Serial No. 323,684.

Figure 4 is an enlarged fragmentary sectional view, on a horizontalplane, through one vertical stile, detailing the stamped sash guides.

illigure 5 is a fragmentary sectional view on a horizontal plane throughthe lower portion showing the sill construction.

Figure 6 is a vertical section taken approximately upon the plane of theline 66 of Figure 4.

Referring now to the drawings by reference characters, it will beobserved that 7 designates a fragmentary portion of the wall of abuilding, 8 the outside bricks or stucco facing, and 9 the plaster.These details are seen in lFi gure 1-.

Observing now the sill structure seen in Figure 2 it will be noted that10 designates the customarystool, 11 the sub-sill, and 12 the cementcaulking. As before indicated, the window frame is of all metalconstruction, for example in F igure 1 the vertical end members 13,which are duplicate in construction, are distinguished as stiles. Alsodisposed vertically and centrally located is the mullion post 14.

At the top of the structure is a horizontal head jamb 15, and at thebottom is a metal sill plate cooperating with and properly shaped to fitupon the cement caulking 12.

This plate as represented in Figure 2 has downturned flanges l7 and isformed at its center with a raised horizontally extending rib 18 whichis filled with cement from the caulking 12. Incidentally, aahorizont aldrain 19 is provided here for moisture escape. This hole is preferablylined with a metal tube, and it is frequently referred to in the tradeas a weep hole. The head jamb 15, also shown in this figure is shaped tofit the building structure andincludes a depression 20 forming a secondhorizontal rib. Thes ribs 1? and 20 cooperate withthe sliding sashes inthe manner to be hereinafter described. As detailed in Figure 3 themullion comprises a hollow metal body or post of general rectangularcross section as indicated at 21 with a suitable inner spacing plate 22.

Considering now the vertical stile detailed in Figure l, it will beobserved that this comlOil prises a metal body of channel shaped crosssection, the open side of which is closed by a flanged closing plate 23.Formed in one side wall is a vertical abutment 24 engaging the bricking8. On the interior, and usually at the bottom are reinforcing angleirons 25. On the inside wall of the stiles is a suitably shaped andproperly welded strip of metal molding 26 cooperating with the plaster9. At a suitable point is a hand hole 27 and a cooperating closing plateor cover 28 therefor. As shown in Figure 6 the upper end is engagedbeneath a depending retaining lip or strip 29, retaining strip 30fitting down into an offset keeper 31 mounted as here shown. This coverplate can be removed to permit access to be had to the interior of thestile. As before stated the stile is intended to form a boxing or ahousing for the pulley cords and sash weights. In this connection weinvite attention to Figure 3 wherein it will be observed that brackets32 are provided for mounting of the pulleys 33 over which the cords 34are trained. The cords carry sash weights 35 suitably attached theretoand the sash weights in turn carry guide eyes 36 movable along guiderods 37 disposed within stiles as herein shown. This insures smoothoperation and prevents binding.

Considering now the window sashes, it will be seen that 38 (see Figure2) designates generally an upper sliding sash, and 39 a lower sash. Bothsashes have substantially the same structural details in their makeup.For instance, a hollow metal frame is employed, the vertical members 40of which are of channel shaped cross section with their open sidesdisposed outwardly to telescopically receive the stamped rib equippedguides 41. For instance this structure is shown in Figure 4 and the sidewalls of the member 40 have sliding contact with the ribs of the guides.The guides are made in the form of separate stampings and either boltedor spot welded in place. Obviously in this double hung sash structure wefind guides mounted on the inner walls of the vertical stiles 13 and onopposite walls of the mullion 14. The portion of the sash frame memberwhich cooperates in the glass panels 42 are bent as shown at 43 inFigure 4. This provides a shoulder against which the glass panel isplaced. Incidentally the reference character 44 designates putty whichserves to partly hold the glass in place. Coo crating with the oppositeor inner side 0 the glass is removable molding 45. The only distinctionbetween the vertical frame members 40 and the top and bottom framemembers 46 and 47, respectively, is that flanged closing strips orelements 48 are fitted into the open sides of the channels. For example,as shown in Figure 2 the lower member 47 of the lower sash 39 has theclosing element 48 spaced inwardly and the lower end carries a rivetedso as to permit the vertical walls of this member 47 to fittelescopically down over the rib 17 which provides a weather proofjoint. The same arrangement is provided for the top sash 38 except thatthere is a reversal in the arrangement of the details as is obvious.Moreover, the top member 46 of the lower sash 39 carries an interlockingflange 49 cooperating with a similar flange 50 on the complementalmember of the sash 38. In other words the meeting rail members of theupper and lower sashes are formed with complemental tongues 49 and 50for interlocking connection to provide a weather and waterproof joint atthis point.

It is perfectly obvious that the gist of the construction here is inproviding a desirable type of joint where the two sashes meet when theyare closed, and to provide desirable joints between the sashes and thewindow frame where these parts cooperate. It is also to be mentionedthat suitable molding 51 is also provided where necessary to produce thedesired finish, and to add to the efiiciency of the construction.

From the foregoing description and drawings it is quite obvious that wehave shown and described a window construction which is economical,practicable in construction and otherwise eflicient in performance infulfilling-the requirements of an invention of this class in apracticable and modern manner.

It is thought however that persons skilled in the art to which theinvention relates will be able to obtain a clear understanding of thesame after considering the description with the drawings. Therefore, amore lengthy de scription is regarded unnecessary.

Minor changes in shape, size and rearrangement of parts coming withinthe field of the invention claimed may be resorted to in actualpractice, if desired.

Having thus described the invention, what we claim as new is:

1. In a window construction of the class described, an all metal windowframe comprising a sill plate adapted for horizontal disposition, a pairof vertically disposed stiles disposed at the opposite ends of andrising from said plate, a mullion post rising from the center of theplate, a head jamb bridging and connected to said stiles and mullionpost, vertically disposed rib equipped guides fastened to said stilesand post, and vertically slidable window sashes including vertical sidemembers slidably contacting said guides, said side members comprisingspaced opposed side walls having a single connecting wall at one endonly thereof adapted to support a pane of glass, the free ends of saidside walls embracing the guides.

2. In a window construction of the class described, a window frameincluding vertical stiles, vertically disposed guides fastened to eachstile, said guides comprising stamped metal plates formed with ribs, andWindow sash including a metal frame, the vertical members of which areof channel shaped cross section and comprise spaced opposed side Wallshaving a pane supporting connecting Wall at one end only, the free endsof said Walls adapted to telescopically receive the ribbed portions ofsaid guide plates.

In testimony whereof We aifix our signatures.
